Sony WH1000-XM2 Black (Used-Like New): Link [amazon.com]
They're pretty comparable to the newest Sony WH1000-XM3 active noise cancellation headphones. They have slightly worst ANC than the newest model but not by much and were considered among the best-in-class not too long ago. Considering the Sony-provided warranty isn't guaranteed with open-boxed items, saving $72 dollars versus the newest is not too bad. Also since the WH1000-XM4 are due to be released anytime, these can be used to tide you over until then.
The headphones are $148.78 before the 20% discount. Note that the discount doesn't show up until you add the headphones to cart and check out. Also make sure the seller is Amazon warehouse. After discount, they will be $119.02 plus taxes.
UPDATE: Headphones are back in stock as of November 28th for $144.23 pre-discount for Like-New condition. This means that they'll be $115.38 after the 20% warehouse discount which is about $3.64 cheaper than before. Limited quantities, so act fast if you really want these!
